I'm learning Angular 2/4 and I see the html tags with the ng generated attributes: _ngcontent-c0, _ngcontent-c1...
What does this c value mean?

attributes are added when you use ViewEncapsulation.Emulated
- which is default. Angular uses these attributes to target specific elements with the styles. The number c
is sort of a unique identifier of the host component. For example, if you have two components with the following templates:
ComponentA
<span></span>
<comp-b></comp-b>
ComponenB
<h1></h1>
Angular will mark all elements with styles inside component A
as _ngcontent-c0
and all elements with styles inside component B
with _ngcontent-c1
:
<comp-a>
<span _ngcontent-c0></span>
<comp-b _ngcontent-c0>
<h1 _ngcontent-c1></h1>
</comp-b>
</comp-a>
